１.在 /etc/my.cnf 下面设置开启bin-log
编辑
vim /etc/my.cnf
[mysqld]
binlog_format = MIXED //binlog日志格式
log_bin =目录/mysql-bin.log //binlog日志名
expire_logs_days = 7 //binlog过期清理时间
#max_binlog_size 100m //binlog每个日志文件大小 最大值和默认是１个Ｇ
binlog-do-db=game #需要备份的数据库名，如果备份多个数据库，重复设置这个选项即可
binlog-do-db=platform #
#binlog-ignore-db=不需要备份的数据库，如果备份多个数据库，重复设置这个选项即可
２.创建远程登陆数据库帐号
grant all privileges on game.* to 'jack'@'192.168.10.56' identified by 'admin'
grant all privileges on platform.* to 'jack'@'192.168.10.56' identified by 'admin'
3.将服务器上的数据，导入一份进远程服务器中
mysqldump -ujack -padmin -h192.168.10.38 > 备份数据库地址(/home/mysql/db/mysql.sql);
4.写Ｌinux 计划任务:
vim /etc/crontab
在底部加入
0 3 * * * root sh /home/wwwroot/sh/mysqlbackup.sh #每天3点以root帐号的权限执行目录下的sh
重启服务
/etc/init.d/crond restart
---------------------------------------------------
如果遇到了问题，请查看一下
select super_priv,user from user where host='192.168.10.39';
update user set super_priv='Y' where user='game1';
